Future Diary Wiki

John Bacchus (ジョン バックス, Jon Bakkusu, John Balks in the English dub) is the Eleventh diary owner, and the final owner revealed in the series. The Mayor of Sakurami City, John Bacchus is the actual creator of the Future Diaries technology and suggested the concept of the survival game to Deus Ex Machina. He put the first Future Diaries together to create his own "Watcher Diary".

Appearance & Personality


John is a middle-aged bespectacled gentleman dressed in fine clothes and wearing a hat resembling a Jewish kippah. Using his position as mayor of Sakurami City, John is the most powerful man in the city and his influence is very strong. In his opening scene, John convinces the entire city council to agree to shut down Kamado Ueshita's orphanage by crying crocodile tears and blubbering about how he adores every child in the city as if they were his own. John is obviously intelligent and manipulative, but can be just as honest.

He is very polite and acts like a gentleman towards Kamado. However, he is perhaps one of the more ruthless of the twelve diary owners, being strategic and using his intelligence to use the outcome of any situation to his advantage. His goal in the game is to help humanity evolve to a higher form of being by having every citizen have an Apprentice Future Diary, sharing similar beliefs to the Macedonians, Romans and Nazi Germany.

Diary & Abilities

John using The Watcher

John's diary is known as The Watcher. It is a tablet that allows him to check the entries of every Diary User, be it a Survival Game participant or an Apprentice Diary User. This gives him several advantages, such as being able to track the position of his foes as well as prepare countermeasures if an entry suggests he's in danger. While very powerful, it cannot identify misinformation; thus, Diary Users can simply rewrite their entries to trick The Watcher. It is also unclear if it can read entries on Diaries manifested as non-electric devices (such as the Diaries used by the Fifth and Sixth), although Deus himself claims that it can read any Diary; presumably, it has a supernatural means of doing so for non-electronic Diaries.

Being the Mayor of Sakurami City, John has great power and influence in the city's politics; he is also wealthy enough to have his own personal guard. He once used his influence to shut down the Mother's Home in order to corner The Eighth into joining him, which shows he also has great intelligence and is a skilled manipulator. The greatest demonstration of his wealth is with the Holon supercomputer, which has 3 servers and is overall Japan's third most powerful supercomputer. He has his personal guard cover 2 whole floors on his towers and still have a large amount of men to defend him as well as the needed weaponry. Knowing he would face eventually face the Eighth, he had a jammer attached to his personal car to cut the connection to the Server's Diary and leave the orphans defenseless.

His power is great enough to have access to information and codes only known to Yuno's dead parents, which served to protect him behind a Bank Safe.

Muru Muru once said that John had a 91.02% chance of being the winner of the Survival Game, and he is arguably the most powerful of the participants at the time of his full introduction.

Plot Overview


John Bacchus and Deus formulated the survival game.

John, wishing to evolve humanity to new heights, met and approached Deus with the proposal to give mankind some of his divine power. His concept was the Future Diaries, which could predict the future. Learning of Deus' approaching demise, John's idea would contribute to the survival game Deus had in mind to choose a successor. Deus used his powers to help create the powers of the Future Diaries, whilst John developed the actual technology. The two made several archetypal prototypes to test out the powers of the diaries - The "Radar" Diary, which could predict a person's surroundings; the "Searcher Diary" which predicts the actions of certain individuals; the "Organizer" Diary which predicts the actions of groups; and the "Supplier" which gives others the power to predict the future.

Using the data of these original Diaries, John formed a fifth prototype, the "Watcher" Diary, in order to watch and record the activities of all other diaries. This effectively made John the first Future Diary owner in the Second World's Survival Game, despite being officially designated as the Eleventh.

John debuted with the other diary owners during Deus' first meeting of the survival game, targeting Yukiteru Amano as the primary target to eliminate after he killed the Third owner Takao Hiyama. He is present at the second meeting, and other subsequent ones, although he does not make a move in the game until later on, likely observing the other owners until half of them are eliminated.

The Seventh's Battle of Love

John begins to make his move against the other diary owners, manipulating Kurou Amano into his services by telling him that if he destroys Yuki's diary, his debts will be cleared. However Kurou fails because of the interference of Marco Ikusaba and Ai Mikami who had used fake cellphones to mislead Yuki and Yuno however saving Yuki in the end when Kurou breaks the fake instead of the real one.

The Eleventh's Kingdom

After Kurou's failure, John has his subordinates attempt an assassination of him and Yuki. Kurou is killed, but Yuki uses his diary to kill the men, prompting him to play the game after all and target John. John makes his plans to eliminate Kamado next, convincing the council of Sakurami City to shut down her orphanage after the incidents involving the residents.

At the final meeting held between the last diary owners, John suggests to Deus to eliminate Yuki and Yuno Gasai from the game after they have not made an appearance in five days, although Minene Uryu objects. As Deus is about to follow John's request, Yuki and Yuno arrive, Yuki revealing John's identity to the other owners and vows to kill him in order to avenge his parents. Forming an alliance with Kamado, Yuki and Yuno plan to ambush John whilst he is on his way through a country road, guarded by Masumi Nishijima. However, John anticipates the attack and uses an EMP weapon to disable Kamado's Apprentice Diaries. Yuki and Yuno then turn against Kamado, killing her orphans, causing her to flee. However, John and Nishijima pull over in their car, offering Kamado a ride.

John fending off Yuno and Yukiteru

John and Kamado make their getaway, Yuki and Yuno giving chase in a car down the motorway. Yuki eventually rams John's car until it crashes, allowing her to confront the Eleventh directly. Despite having a gun aimed at his head, but John merely mocks her as Minene arrives with Aru Akise, carrying with him the umbilical cord of the "real" Yuno Gasai, something which John takes note of. He tries to shoot Yuno but Yuki flees with her. Several nights later, John takes Kamado to the city's university where he reveals the HOLON III supercomputer. He explains his plan to Kamado - to connect her Blog Diary to the supercomputer, so every citizen in Sakurami City can become Apprentice Diary owners, allowing him to create a superior race of human beings like Macedonia, Rome and Nazi Germany tried to do. Minene, who is spying on the conversation, calls him a maniac and tries to throw a grenade at him. John immediately catches it and tosses it back, causing Minene to flee. However, Minene and Nishijima are able to destroy the computer terminals, believing they have defeated John. That is until a policeman speaks on Nishijima's radio, claiming his phone is telling him of his future, Holon III actually possessing two more terminals.

Learning John is keeping the other two Holon terminals in conjoined twin buildings, Minene plots to blow them up and then to kill him. She learns of the abilities of John's Watcher Diary and his past from Deus, and initiates Operation Starling to defeat John. Teaming up with Nishijima, Hinata Hino, Mao Nonosaka and Ouji Kosaka, Minene leads the group up the two buildings, each of them adding false entries into the Future and Apprentice Diaries to confuse John and his men, misinformation being the Watcher Diary's weakness.

However, with help from his assistant Ryuji Kurosaki, John is able to deduce Minene's plan and plants a claymore mine in her path. Minene is caught in the explosion and loses an arm, whilst Nishijima is gunned down by John's men. Hinata, Mao and Kosaka are also caught. However, Yuki and Yuno arrive and split up to eliminate John and Kamado, the latter hiding in the terminal room in the southern tower. Yuki contacts a news crew to send a message to John via a helicopter, instructing him to commit suicide, but John is able to reverse the situation and dismiss the news crew. Yuki and Minene race to stop John, only to witness him and Kurosaki disappearing into a bank once owned by Yuno's adoptive parents.

John and Kurosaki seal themselves inside the bank's vault behind a door made of solid steel. Yuki and Minene try to figure out the password, Yuki managing to stage his own future to follow Kurosaki and learn the password to the vault, correctly identifying. He successfully enters the password, John shooting Kurosaki dead so Yuki cannot obtain any more details. Using the password and a security key, Yuki opens the vault door only to discover there is a second vault door between him and John. Yuki and Minene get into a gunfight and run off, leaving John safe until Yuki returns with Yuno. John continues to believe that Yuno is an impersonator, knowing the only way to open the second vault door is through a retinal scanner that only works for John himself, Yuno's parents, and the real Yuno.

John speaks to Yuki over an intercom system, mocking Yuki and his parents as being useless "samples" of the superior race he wishes to create through the Apprentice Diaries. John advices Yuki to escape through the underground waterway, continuously mocking him for being a crybaby. Minene returns, having been shot by Yuki and is close to dying. Stumbling into the gap between the vault doors, Minene produces an explosive which will detonate when her heart stops, planning to blow apart the doors to allow access to John. Minene destroys her diary and activates the bomb, blowing open the first vault door and dies. However, it is revealed that the second vault still remains closed. John mocks Minene's failed sacrifice, and a despairing Yuki is dragged away by Yuno.

Yuno places Yuki in the underground waterway, and disappears. In the vault, John prepares to leave but notes Yuno's diary entry mentions her planning to kill him. John turns around, only to see the second vault door opening. To his horror, Yuno is revealed to have used the retinal scanner, revealing her to be the real Yuno Gasai after all. John only has time to register his disbelief as Yuno runs at him, armed with a sword, and swiftly decapitates him. Yuno later tells Yuki she killed John when he emerged from the vault to cover up her own deceptions. John's dream eventually ends with Kamado's death several days later, and the destruction of the world.

In the anime, after Minene's failed attempt to blow herself up and the vault door, Yuno sends Yuki off to destroy Holon III whilst she waits outside the vault. However, Yuno opens the second vault door using the retinal scanner and shoots John through the head with a gun.

The Final Battle

John appears in the third parallel world when Yuki, Yuno, Minene and Muru Muru perform a time leap back two years into the past. John witnesses the explosions at the elementary school, having already designed his early Future Diaries. Telephoning Kamado at her orphanage, John informs her he is going to start giving her council funds to the orphanage, for the sake of the future. John ends the call, telling Kurosaki changing the future is necessary, having read Yuki's Future Diary and learnt of his death in the future, impressed his technology could show the diaries of a person from another world. John visits the third version of Deus and reveals that he is cancelling his Future Diary project, thus, cancelling the future survival game of the third world.

Two years later, after the original Yuno's suicide, John is seen in the company of Kamado. They walk down a street together with other characters, possibly a couple due to John's happy expression, or they are merely working together to make Sakurami City a better place. In the anime he is seen taking Kamado with him, suggesting they are in fact engaged.


  • John Bacchus is named after Bacchus, the Roman god of wine, better known as the Greek god Dionysus. Bacchus was described as a god of "foreignness" due to his arrival as an outsider-god in the mythology; similarly, John is foreign and follows the ideals of countries like Rome, Macedonia and Germany.
  • John's character theme song is "Herrscher" by Yousei Teikoku. The song is sung in Japanese and German. Herrscher is German for "ruler".
  • John Bacchus is the only known character in the series who doesn't have a Japanese name and instead, has a Western-styled name.
  • In the Redial OVA, when giving "game" ideas to Deus, he is seen holding what looks like a Death Note in one scene, suggesting one of his games would be a "Future Note" of some sorts.
